Changing Between 32-bit and 64-bit Gaia VM

When you install Security Gateway Virtual Edition on a Gaia computer or VM, a 32-bit kernel installs by default. You can change it to 64-bit with Edition.

Note: The ESX server hardware must support 64-bit.

To change to 64-bit Gaia:

1. Turn off the Security Gateway Virtual Edition VM.
2. Increase the Security Gateway Virtual Edition VM memory to 6 GB or more.
3. In the Gaia command line, run: set edition 64-bit
4. Turn on the Security Gateway Virtual Edition VM.

To see which edition is running:

In the Gaia command line, run: show version os edition

Installing Clusters

Security Gateway Virtual Edition supports clusters of two or more members. If you install cluster members on different ESX hosts, you can be sure of automatic failover if an ESX host is unavailable.

You can use VMware High Availability or other failover solutions for VMs only. VMware High Availability and other VMware clustering solutions do not work with state synchronization for Security Gateway clusters.

Defining a ClusterXL Cluster

For ClusterXL details, see the R77 ClusterXL Administration Guide.

To define a ClusterXL cluster:

1. Install and configure two or more Security Gateway Virtual Edition VMs.
2. Turn on the VMs.
3. Run the First Time Configuration Wizard on each member. Make sure that cluster support is active.
4. Make sure that there is connectivity between the cluster members and the Security Management Server. Resolve connectivity issues before continuing.
5. Make sure that there is connectivity between the cluster members and internal networks, external networks, and other VMs. Resolve connectivity issues before continuing.
6. Use SmartDashboard to define the cluster as an object and to configure its synchronization networks.
7. Define and install security policies.

Increasing the Security Gateway Virtual Edition Disk Size

Add a hard disk to the Security Gateway Virtual Edition VM to give space for backups.

Creating a Second Hard Drive in VMware

You cannot change the size of the hard disk in an existing Security Gateway Virtual Edition VM. But you can add a disk drive to a VM.

To define a second hard drive:

1. Turn off the Security Gateway Virtual Edition VM.
2. Right-click the VM in your inventory and select Edit Settings.
3. Click Add.
4. In the Add Hardware Wizard, select Hard Disk.
5. In the Device Type window, select Create a new virtual disk.
6. In the Select a Disk window, enter the disk size in gigabytes.
7. In the Advanced Options window, click Next.
8. In the Ready to Complete window, click Finish.

Configuring New Hard Drive in Gaia

You can format the new drive and configure Security Management Server to send the log files to the new disk. First, create a new partition. Then, define the volume settings.

To create a new partition:

1. Log in to the host console in expert mode.
2. Create a new partition. Run: fdisk /dev/sdb
3. Enter n to add a new partition.
4. Enter p to choose a primary partition.
5. Enter the partition number (1 for a second disk).
6. Accept the defaults for the first and last cylinder.
7. Enter t to change the partition’s system ID.
8. Enter the hex value: 83.
9. Enter w to write the partition table to disk and to exit.

To define volume settings, run these commands:

Example:

fdisk -1

pvcreate /dev/sdb1

vgcreate mynew_vg /dev/sdb1

lvcreate -L 4000 -n vol2 mynew_vg
